Revert configuration from file based to database based

The D8 project I'm currently working on used the file-system based workflow for configuration management. As our deployment workflow improved and got slightly more complex, we started to run into issues with file permissions during deployments and wanted to revert back to the database based workflow that is the default for a new D8 installation.

jQuery version per theme

Recently I came across something that feels like a bug in the jQuery Update module. The current version allows to specify a modern jQuery version to use for a site, which is awesome when you want to include modern user interface functionality using jQuery UI. Additionally the module allows to override the jQuery version that should be used, but only for admin pages (introduced after a rather long issue discussion).
